Title: Improvements in or relating to the separation of gold from auriferous gravel or other ore
IPC: B03B5/56
Filed: 1921-08-23
Abstract: 189,206. Dyson, L. M., (Newton, R. F.). Aug. 23, 1921. Rotary washing-apparatus.-Gold is separated from gravel or like ore by treatment in a substantially horizontal rotating cylinder provided on its interior with a lining of blanket material, and w i t h longitudinal riffles which are preferably inclined backwards from a radial position in order to carry the auriferous pulp to the top of the cylinder and to prevent it from sliding back into the mass of the ore. The coarsest gravel is first separated from the remainder by trommelling or the like, and the fine gravel, mixed with water, is fed by a shoot 10 into the rotating cylinder 1, which may be circular or polygonal in cross section. The latter is divided longitudinally, being hinged at 2 and secured by a hasp fastening 3. Surrounding the cylinder are iron flanges 4 resting on the rollers 5, the rotation in the direction shown by the arrow r being effected by a direct belt drive on the pulley 8. Water is sprayed on to the mixture, when it reaches the top of the cylinder, through perforations 12 in the upper surface of a feed pipe 11. Secured to the latter is a longitudinal shallow trough 13 extending as far across the top of the cylinder as the riffles 9 will permit. The water, gold and adhering fine sand, falls into this trough and is led away for further treatment by amalgamation, cyaniding, or the like. Specification 140,266 is referred to.

Abstract: 205,624. Jardine, Sir E., Watchorn, E., and Jones, F. H. Haslam-. Aug. 21, 1922. Lace machines.-For the production of fabrics which resemble woven fabrics more closely in structure than ordinary twist lace, weft-thread laying devices mounted on carriers and operated by cables and pulley gear are provided. The bobbin-carriage actuating mechanism is modified so as to give a dwell. The cranks S which impart the primary movement to the catch-bar mechanism each work in a slot T<1> in an oscillating arm T to which the link V is connected. The curve of the slot T' coincides with the path of the crank pin at one part of its revolution and thus provides a dwell, which is timed to occur while the wefts are laid. Each thread-layer A is mounted on a carrier B which travels on wires C disposed below, say, the front comb bar D. The carriers B are connected to a cable E which runs under a pulley J on a bracket H at one end of the machine and round two sets of sheaves F, G, the end of the cable being secured at H<1>. There is a similar arrangement at the other end of the machine, so that when the pulley block G<2> at one end is pulled down the other pulley block is drawn up.

Abstract: 409,185. Shaping capsules. BRUUN, O. J., 25, Kongensvej, Frederiksberg, near Copenhagen. Aug. 15, 1933, No. 22762. [Class 100 (ii).] In a machine for making corrugated metal-foil capsules of the kind in which a fluted plunger 7 encircled by a resiliently-supported fluted annular piston or pistons 8, 8<1> cooperates with a fluted funnel-sliaped die so that the pistons are moved backwardly against increasing spring- pressure as the piston and die are moved relatively to one another, each piston 8, 8<1> is capable of tilting from a normal coaxial position with respect to the plunger as a result of unevenly applied pressure. The plunger 7 is attached by a stud 18 and nut 20 to a base member 16 secured to the fixed casing 9, a rubber ring 21 and a hemispherical block 22 being fitted between the parts 7, 16 so as to enable the plunger 7 to yield and cause the pressure to be applied evenly. As an alternative, a rubber washer may be inserted between the base 16 and the casing 9. Each piston is supported by three equidistant rods, those 28 for the piston 8 passing through holes in the casing 9 and bearing against a plate 42 loosely mounted on a rod 41 carrying an adjustable spring 44 pressing against the plate. By means of nuts 36, 37, the rods 28 and therefore the piston 8 may be adjusted. The rods 28<1> supporting the piston 8<1> bear against adjustable springs 39 in casings 38 and are adjusted by nuts 36<1>, 37<1> and a stud 40. The outer end 29 of each rod 28, 28<1> is reduced to pass through a hole 30 of larger size in the corresponding piston. A pin 32 and spring-washer 34 on opposite faces of each piston connect the rods loosely to the pistons so as to allow the pistons to tilt slightly, the pistons being spaced as shown at 23, 24, 25, 25<1> to permit of the tilting. An annular knife 11 is secured to casing 9 by bolt-and-slot connections 46, 47 and is adjusted by three radial set-screws 45. The material may be fed by a pair of rollers one of which may have a finely grained or fluted surface. Either the plunger or the die may be movable, the other part being fixed.

Strainer separators; feeding and discharging. - A centrifugal separator has a feeding chamber and the entry of the material to the basket is controlled by the pressure of the material in the chamber. The separator has an inner imperforate drum A and an outer perforated drum B in a fixed casing C. The drums are arranged to rotate at different speeds and the drum A carries a helical rib 4 which contains a number of plunger scrapers 3. Each scraper is connected to a piston 37, Fig. 3, and is normally withdrawn from the drum B by a spring 36. The scrapers are moved into the operating position shown in Fig. 3 by compressed air which is supplied to the channel 32 through the regulator R', Fig. 2, chest 26, and central tube 24. Steam is used to clear the drum of the thin layer of material left by the scapers and is supplied to outlet tubes 2 in the rib 4 through the regulator R, chest 27 and tube 23. Brushes 47 are also provided on the rim. Liquid passes through the drum B and is collected by the trough 63, while the solids pass through the gaps 38 into discharge conduits 39 which may be closed by gates 45, 46. A door is arranged in the wall of the drum B and another 21, Fig. 1, is arranged in the casing C. A chamber P is arranged at the top of the casing, and it opens on to the top of the inner drum A. The top of the chamber may be closed by doors 42, 43 on a hinge 44. Pistons 5, 6 are arranged in cylinders in the wall of the chamber and are held level with the wall, as shown in Fig. 11, by springs 7, 8. Each piston carries a contact which can touch a fixed contact to complete the circuit of an electromagnet 13. This operates its core to close the valve N. When the machine starts the valve N is opened manually and material passes from the trough S to the chamber P and the space between the drums A, B. If the pressure in the chamber P rises sufficiently, the pistons 5, 6 operate to close the circuit of the electromagnet which closes the valve N and stops the flow of material.
